CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 412,706, dated October8, 1889.

Application filed August 9,1889. Serial No. 320,269. (No model.)

To all whom it may concern.-

Be it known that I, IVORY HAZELTON, of Boston, in the county of Suffolkand State of Massachusetts, have invented a new and useful Improvementin Car-Couplings, of which the following is a specification.

This invention relates to that class of couplers which are known asengine-couplers and are intended to be secured to the rear end of thetender, and by which the engine similar letters of reference indicatelike parts,

Figure 1 is a side elevation of an engine-coupler similar to thatdescribed in the patent above referred to with my buffers applied to it.Fig. 2 is a plan view of the same. Fig. 3 is a view in perspective ofone of the buffers removed. Fig. 4is ahorizontal cross-section of thesame. r

A A is the frame of the coupler, made in ,two wings, as shown. B is thefoot board,

and O the head of the draw-bar, all constructed substantially asdescribed in the Letters Patent above referred to, and not new in mypresent invention.

Suspended in front of the frame on each side of the draw-bar, andsecured to the upper edge of said frame by means of hooks d,

in any desired manner which will allow of the buffers being swung uponthe frame, as shown in broken lines, Fig. 1,are my buifers. Each ofthese buffers consists of a metallic case or shell D, open at the rear,and preferably at the bottom, and a block of rubber D. This case D, as-will be seen, covers the top, front, and sides of the rubber block orcushion D,and said block of rubber projects rearward a little beyond thecase, so as to have room to contract without the shell coming intocontact with the frame of the coupler. The hooks cl catch over suitableears cl or other practicable devices, and when the buffers are not inuse they allow of their being swung up out of the way in the positionshown in broken lines, Fig. 1. When such buffers are in position foruse, however,

they serve very effectually in preventing the shock from the coupling onof a freight-car or train from injuring the tender or the coupler.

Having thus fully describedmy invention, what I claim, and desire tosecure by Letters Patent, is

The combination, with the frame A of the coupler, of the bufferdescribed, consisting of the metallic case or shell D, open at its rearside and suspended in front of said frame, and the rubber block orcushion D, inclosed in said shell and projecting slightly rearwardtherefrom, substantially as and for the purpose set forth.
